ORNAMENT ING MACHINE 4 Filed April 5, 1938 6 Sheets-Sheet 6 Patented May 13, 1941 UNIT s'r'rss PATENT OFFICE 55 Claims.

This invention relates'to machines for use in the manufacture of boots and shoes, and more particularly to combined marking and cutting machines adapted for operations upon skins, upper blanks, fitted or closed uppers and the like, in which the work is marked with ink, pigment, or its equivalent, at the same time or as part of a cycle of operations, during which the work is also ornamented by perforating or cutting out a design therein, the cutting and marking preferably being performed as a single factory operation.

The present invention is directed to improvements upon devices and machines for effecting the mentioned operations, as described and claimed in the patents to Benjamin W. Freeman, No. 2,084,335, dated June 22, 1937, and Benjamin W. Freeman et a1, Reissue No. 20,294, dated March 16, 1937, and the co-pending application of Benjamin W. Freeman, Serial No. 83,796, filed June 5, 1936, to which reference is hereby made.

These machines are of a type intended for use as universal cutout and marking machines, specifically intended for'work on shoes, leather, and shoe materials, where the work is of widely varying contour and design, the machinesbeing designed to operate, not only upon fiat material, but also to perform operations on other than fiat work, such as closed and fitted uppers or other types of ring-like work.

Objects of the invention include the formation of ornamental designs in the work, by the application of a stamped or printed marking which may simulate stitching, or may take the form of a design, or by the formation of ornamental cutouts in the work, or by combinations of both markings and. perforations: or cutouts; and the accomplishment of the marking and cutting operations either simultaneously or during a continuous cycle of operations.

Reference to stamped or printed markings is made herein because of its universal adaptation to all types of leather; however, the present invention is likewise readily adaptable to the production of other forms of marking, e. g., impression or indentation of the work. It is a further object herein to provide means for changing from one form of marking to another by a slight adjustment, and without necessitating change of any part of the machine.

A still further object contemplates the application of markings which may be used to form a printed ornamental pattern, or as a guide for subsequent operations on the shoe parts, such as aligning the parts relative to each other,

stitching, etc., the markings being applied at such a time and in such a location with reference to the cutouts as to insure accuracy in the subsequent operations with relation to the cutout portions of the work. a

While it is contemplated further that the marking device may be combined with, or form a part of the conventional stripper plate which is normally designed for stripping the work from the cutting edges of the die, it is also an object to provide a marking device which may operate in conjunction with the'cutting or perforating elements of the die without in any substantial measure applying a stripping pressure to the work.

An automatic inker is provided for the application of ink or equivalent marking medium, to the marking portions of the die, and by means of which ink is applied to the die with every stroke of the plunger, i. e., in timed relation thereto. The invention contemplates, among its objects, an ink roll organization by means of which the level of the ink roll can be varied, control of pressures of the roll against the die, for light or heavy marking, is attained, and ink is replenished and supplied to the ink roll for transfer to the die, with every stroke of the plunger.

Various safety mechanisms assuring a predetermined cycle of operations, and designed to prevent injury to an operator or to the work by preventing premature, delayed or inaccurate operations form a feature of this invention.

As described in the aforesaid copending applications, and illustrated herein, a preferred embodiment of the machine has a power driven plunger movable through a relatively vertical plane, the plunger serving to mount a Work support on which the work may be accurately positioned by means of suitable gaging devices.

A die which is relatively fixed insofar as vertical movement toward the work supporting plunger is provided, and this die is arranged to move into and out of "an operative relation to the plunger, the movements however, being confined to a substantially horizontal plane in the illustrated embodiment. Means are also provided for retaining the die against movement in any direction should it be desired to so operate the machine.

In order to effect the movements of the die, there is provided a carriage which is actuated electrically, preferably through the medium of an electro-magnetic clutch, whereby instant and complete control of the carriage movements and position are obtained.

chine actuates the plunger by means of which the cutters of the die are forced through the work, and it follows that the paper feed takes place during the movement of the plunger. However, the backing medium must not be fed while the die is contacting the work and therefore the feeding'of the paper must take place in only a part of the cycle. Most of these machines operate at about 200 to 350 R. P. M. so that there are many limitations to suchstructure, and an important object of the present invention is to provide a paper feed which is operated and controlled independently of the crank shaft, or other operating parts of the machine, and not limited by the cycle period thereof.

In the preferred form illustrated herein, the paper feed mechanism is driven by the same motor that, actuates the plunger, but it will be noted that an intervening clutch is provided which might be termed a'magnetic paper feed clutch and this makes it possible to use the power at any designated time.

The paper feed parts move so fast that there is a great deal of wear and breakage. The amount of paper that can be fed in the short time available is limited and with large. dies on certain machines of this general type it has been impossible to provide sufiicient feed for the paper, so the operator was obliged to treadle the machine a time or two Without the die in operative relation to the plunger. In other cases, the feeding of the paper is dispensed with, and instead of using a roll of backing paper ina customary'manner, pieces of the backing material are cut to a suitable size to accommodate the die,

and handled separately in this manner during each cut, a separate piece of backing paper being used eachtime or in some cases several times.

With an independent feed, it is possible to regulate the amount and time of feed, and also to provide a smooth even feed, and accordingly objects of the invention include a mechanism for feeding a sufficient amount of paper as may be required, and for feeding the paper without a jerky movement, through a nice smooth action.-

The feed may take place while the operator is moving the work, and during a portion of the cycle when the plunger is not operating at all.

Still another object contemplates a control mechanism for the paper feed through the medium of electro-magnetic clutches whereby the timing and length of feed may be regulated to a very fine degree.

Gauging devices are provided for aligning the work relative to the die and these gauges may be carried by the work support, by the die, or otherwise interposed between the work supporting surface and the die. The gauging device may take the form of a mask effective to clamp or hold the work in its aligned position; in fact, it is contemplated that a mask or clamp having no gauging function may cooperate with any desired type of gauge for this purpose. Y

A single control, as a treadle or its equivalent, is preferably utilized for the mechanism by means of which the die may be moved into an operating position, the marking elements of the die inked, the main clutch of the machine released, the work support and plunger raised to effect an operation on the work, and return, and the die thereafter moved to a position away from an operator who may then remove the work from the machine.

The broad principles and mechanisms for accomplishing these several results under a single control are illustrated in the aforesaid patents and application, and the improvements herein described aim toward simplification of such mechanisms and improvement in certain constructions going to the make up of the complete machine, such as the backing paper support and feed mechanism, adjustments in the inking roll mechanism, control of the plunger by movements of the die carriage together with control of the die carriage by the plunger, in the mode of attaching and locking a die in the machine, together with safety means preventing operation of the machine at all times, except when the die is accurately positioned and locked in such position, in improvements in the die carriage driving mechanism, together with certain adjustments by means of which accuracy to a fine degree in the travel of the die may be accomplished regardless of wear in the machine, and in improvements upon the automatic control means synchronizing operation of the various mechanisms.

It is an object to provide electrical controls for the various moving parts which are in themselves under the control of certain of the moving parts, e. g., the paper feed is regulated in its timing and duration by an electro-magnetic clutch, the current for which is under the control of the die carriage.

While the present invention relates specifically to improvements over the machine of the said patents and application, the general aims and objects as set forth therein are however, retained.

Ornamenting machines for forming cutouts in a work piece, or for making same, or for effecting both operations are of course known, but the .present machine is designed to meet increasing demands of work and operating pressures without increasing the sizeof the machine itself to an impractical degree.

In commenting upon the universal features of this machine it should be noted that the structure is readily adaptable to various types of dies and to various operations. For example, the die may be mounted to cut up or down, or in lieu of a die mounted within the machine, a selfcontained auxiliary type of die and paper feed mechanism may be utilized by placement of such auxiliary unit upon the work support, which will then act to move the auxiliary unit with the work thereon toward the head of the machine, which head will function as a resistance or reaction member.

Another improvement contemplates automatic control of movements of the operating plunger, die carriage, feed of backing medium, and other portions of the machine, whereby to obtain a more perfect synchronism and accurate relation of parts.

Among the main or principal features of the preferred form of machine are a substantial difference in the arrangement of parts'over prior ant machines which endeavor to obtain similar results, i. e., the operating plunger partakes of a movement through a generally vertical plane, the die unit remaining fixed, insofar as the plane of travel of the work support is concerned, while being movable through a substantially horizontal plane into and out of operating position,

Such arrangement permits maintenance of necessary clearance between the die and. work support, facilitates changing of dies in the machine, fitting of the work into proper position, and inking of the marking elements. It also permits a decrease in the operating stroke of the plunger, as compared with prior art machines, and avoids excessive inertia in moving parts. Furthermore, where it was essential from the standpoint of safety in many prior art machines, that the operator wait until all moving parts had come to rest, with the present ap paratus the operator may be handling the work in perfect safety even though the die is still moving to its inoperative position after cutting or marking the work.

One of the most important features of the present invention relates to the mechanism and method. of stripping the work from the die. Conventional strippers include some mechanism directly associated with the die unit, e. g., a stripper plate mounted on springs which serve to normally maintain the plate in a position slightly in advance of the cutting edge of the die. The spring pressure must be so adjusted as to accommodate varying thicknesses of leather or other material upon which the die is working and difficulties arise in this connection, particularly when marking edges are placed on the stripper. Thus if the spring pressure is adjusted to mark and strip properly a light piece of calfskin, it would probably injure a heavy piece of leather. Obviously, when the material is thick, the stripper will be depressed by the material, more than would be the case with thin leather. Varying pressures are required with different characters of leather as well as with different thicknesses, and as the number of cutouts or perforations in a piece of work is increased, the need for greater pressure likewise increases, and such pressures are very difficult of attainment with the conventional stripping devices now in use.

These difficulties and objections have been largely overcome by my patented methods and devices for ink marking and. cutting, mentioned in the aforesaid application, but even they are limited as to the treatment of extremely heavy work, requiring heretofore unheard of pressures in such machines. In other words, some desired types of work require pressures too great for satisfactory stripping,

In the solution of these problems, particularly that of extreme pressures, the present invention contemplates a stripping mechanism wherein the pressure is applied by an arrangment independent of any particular die, this being accomplished by building a stripper pressure applying mechanism into the machine, as distinguished from supplying an individual die with a self-contained, complete stripping arrangement. The usual stripper plate, mounted in advance of the cutters, is retained.

To the attainment of the foregoing and. other objects which will appear as the description proceeds, reference may be made to the accompanying drawings, in which:

Fig. 1 is a side elevation of a preferred form of machine;

Fig. 6 is a front elevation of the ink applying mechanism;

Fig. '7 is a side elevation partly in section of the driving mechanism for the die carriage;

Fig. 8 is a top plane partly in section of the carriage driving mechanism; and

Fig. 9 is a rear elevation thereof.

General organization Referring now more specifically to the drawings in which like reference numerals designate like parts, there is disclosed a main frame or housing l0 mounted upon a base designated generally at H. A work supporting plunger 12 is mounted in the frame for vertical reciprocation, being actuated in the manner described in the patents and application mentioned above. A die holder or carriage i3 is mounted for sliding movement upon a track or guideway l ll4 for horizontal reciprocating movement from an inoperative position at the rear of the machine to an operating position over the work support. Suitable anti-friction bearings will preferably be supplied for mounting the carriage upon the track.

Various styles of die may be mounted upon the under face of the die carriage, and suitably secured in place. Examples of such dies and the details of mounting and securing the die will be found in the aforementioned patents.

Power may be supplied to the machine through a fly wheel pulley l6 which is mounted for free rotation upon the plunger actuating crank shaft ii. The pulley l6 may be driven from any convenient source of power, a motor i3 being'illustrated. The motor is provided with a pulley [9 which is connected by a belt or belts 20 to the fly wheel I6. The crank shaft i! will be connected to actuate the plunger l2, when clutched to the fly wheel in a manner hereinafter described.

The die carriage may be conveniently driven by a compact driving unit designated generally at 22 mounted at the upper rear of the machine on a shelf or bracket 23, which unit is controlled and actuated as hereinafter described.

Paper feed mechanism The paper feed mechanism, including the driving mechanism for the feed rolls, is best illustrated in Figs. 1 to 4. The paper feed in all ma chines of this nature must be in some manner synchronized with the other operating parts of the machine such that a predetermined amount of paper is fed for each cycle. Heretofore the source of power has usually been the machine drive or main crank shaft. The present invention differentiates by having an independent drive and by being driven from an independent source of power, that is, not directly from the crank shaft of the machine. This eliminates a jerky feed, and permits control of the length of feed and the time that the feeding of the paper takes place in the cycle of operation of the machine.

The driving mechanism for the feedrolls includes a tube 25 mountedat the side of the frame It! (Fig, 2 which extends to a clutch housing 26. The tube 25- is mounted in a bracket 2'! by means of a bearing 28 in which it can rock, and slide a little. The bearing 28 is provided with a stub shaft 29 which is directly mounted in the bracket 21, being freely rotatable or oscillatable therein. With this arrangement the tube would oscillate about the stub shaft 29 as a pivot and also slide slightly in the bearing 28 to accommodate the rocking movement about the stub shaft.

Mounted at the front end of the clutch housing 26, i. e., on the opposite side thereof from the tube 25, is a gear casing 30, and the tube, clutch housing, and gear casing are rigid with each other as a unit rockably mounted in the bracket 21.

A drive pulley 3|, located at the rear end of the tube 25 is secured to a shaft 32 carried by suitable bearings within the tube, and extending into the clutch housing 26.

An electro-magnetic clutch therein, of a generally conventional type, has its hub 33 secured to the end of the shaft 32, and this hub serves to house the usual coil, and to mount commutator rings 34. Suitable contacts 35 are mounted inithe housing for engagement with the commutator rings. A'clutch plate 36 is provided on the combined hub and coil housing 33.

A shaft 31 is aligned with the shaft 32 and extends into the clutch housing from the side opposite the shaft 32, and this shaft 31 serves to mount a second clutch plate 38, whereupon when current is supplied to the coil of the clutch, the plate 38 will be magnetically drawn into engagement with the plate 36. The shaft 31 projects out of the clutch housing and terminates in a head 39. Between the head 39 and a shoulder 4| on the gear casing 39 is a spring 42 which normally pushes the shaft 31 and clutch plate 38 away from the plate 36, the plate 38 being drawn into engagement with the plate 36 against the action of the spring 42 when current is supplied to the clutch.

Splined upon the shaft 37 is a worm 43 which meshes with a worm wheel 44. The worm wheel 44 is keyed to a feed roll drive shaft 45 which extends across the front of the machine and serves to mount and drive the main feed roll 46 (Fig. 3). A second feed r0114! is suitably geared, as at 48, to be driven by the shaft 45. The gear 45 is supported by bearing brackets 49-49, rigid with the plunger I2 and from which depend rigid bearing arms 5l5l The roll 41 is supported by bearing arms 52 pivoted to the brackets 49, and said roll is normally urged toward the main feed roll 46 by resilient spring mountings 53 for the arms 52. A rod 54 is positioned to extend between the arms 52 and abutments 55 on the brackets 49. This rod is provided with flattened portions at the points where it extends between the pivoted bearing arms 52 and the abutment 55, and terminates in a handle 55 by means of which it may be rotated. It follows that by rotation of the rod 54 through the medium of the handle 56, the flattened portions will be turned away, and the full diameter of the rod brought into position between the arms 52 and the abutments 55, thereby separating the same, and separating the two feed rolls 46 and 4! slightly, to permit insertion of the backing web and adjustment of tension, etc. Adjustment of the spring devices 53 will effectively vary the tension of the paper webpassing between the feed rolls, 7

The lower end of the rigid bearing arms 5| serve to mount an idler roll 51, for guiding the web of backing material in its path through the machine. Preferably the paper web will be supported on an idler shaft 50 at the rear of the machine, and a run or web thereof will pass forwardly through the machine across the Work support and back to a rewinder shaft 58 which operates intermittently in conjunction with a step by step feed of the paper.

It will be noted that the feed roll assembly, including the idler roll, gearing between rolls, and the regulating or adjusting devices, is mounted on the plunger l2 and will move therewith. This assembly is, of course, rigid with the worm gearing, clutch and drive shaft at the side of the machine, and movement of this driving mechanism with the plunger and feed roll assembly is accommodated by the pivotal mounting of the tube 25. In other words, with each movement of the plunger, the entire feeding mechanism for the backing material will be given a movement through the extent of movement of the plunger.

Adjustments of the amount of feed of the paper are effected by varying the time that current is fed to the magnetic clutch through the leads or contacts 35. The control of current feed is accomplished as follows: extending along the path of movement of the die carriage is a bus bar mounting 59, and this mounting is pivoted at 50 at the rear of the frame H]. The forward end of the mounting 59 is engaged by a dog pointed adjusting screw 6| threaded through the frame If), and which terminates outside of the frame in a knurled knob 62. A spring 63 connected to the frame I9 and to the mounting 59 maintains engagement between the mounting and the point of the screw 6| from which it can be seen that one end of the mounting may be swung toward and from one side of the die carriage. A pair of spaced, connected contacts 54 located on the die carriage, serve as a means to bridge the bus bars on the mounting 59, and by suitable connections from the bus bar, current will flow to the clutch contacts 35. Such connections would include a lead from one bus bar to a control switch I51, hereinafter described and a lead from the other bus bar to one of the clutch contacts 35. The other clutch contact will of course be properly connected to complete the circuit.

It will be obvious that the contacts 64, being mounted on the die carriage 13, will always move in a straight line, while at the same time the bus bar mounting 59 may be positioned in various lateral angular relations thereto. From this, it will be evident that the duration of contact between the contact elements 84 and the bus bar mounting 59 can be varied as desired, thus varying the length of time that current flows to the clutch contacts 35, and consequently varying the timing and operation of the magnetic clutch 35-38. Variation in the operation of the clutch naturally varies the amount of paper which is fed, and by means of the very slight adjustment through the dog pointed screw 5 I, the paper feed may be controlled, both in duration and time of starting.

The contacts 64 are preferably spring mounted for proper engagement with the bus bar mounting 59, and are headed internally to limit their outward extent of movement. This permits a yielding movement necessitated by the angular position of the bus bar mounting with respect to the straight line travel of the die carriage, to maintain a proper engagement from an extreme outward position of the contacts 54 to the limit of inner movement thereof, as the carriage travels along.

The source of power for driving the pulley 3| is, as stated above, the motor l8. This motor is mounted on a shiftable platform 65 which is provided with an adjusting device 66 effective to raise or lower the motor and thus vary the tension placed upon the various belt gearing extending from the motor.

In addition to the pulley 19 which serves to drive the fly Wheel pulley I6, there is a second pulley 61 on the motor shaft which actuates or drives a belting 68. The belt 68 passes over angularly related idler pulleys 69 and 10 around the corner of the frame of the machine to the nulley 3|.

From the foregoing it will be noted that while the motor I8 furnishes all the power in the illustrated embodiment, for operating the entire machine, that because of the magnetic clutch 36-38 and the control thereof, the paper feed drive is independentand distinct from any other machine operation, and is under a separate and independent control. This is just as true as though there were no self-containing source of power such as the motor l8 in the machine at all, as would be the case were the fly wheel pulley l6 driven from an over head factory belt gearing system, and the paper feed mechanism driven from a separate motor, or from a central source of power in a factory. I

Die inking mechanism The mechanism for applying ink to the mark ing elements of the die unit is best illustrated in Figs. 1, 2, and 6. In order to apply ink to the marking elements of the die there is provided an inking mechanism including a main ink roll 13, mounted adjustably in brackets M. The adjustable mounting is similar to that. in application, Serial No. 83,796, and consists in a spring arrangement 15 below the roll shaft and an adjusting screw 16 above. Between the spring 15 and the adjusting screw 16, on each bracket H, is a bearing box 1'! which receives the shaft or studs 18 for the roll 13, and with this arrangement, the level of the roll i3 can be varied at either or both ends of the roll, to ensure even application of ink to the marking elements of the die.

The brackets 14 also carry adjustable arms 19 which in turn support a distributor roll 8!] (Fig. 5). An adjusting device 81 serves to regulate the pressure between the main roll '13 and the distributor roll 8!. l

The brackets 14 are supported upon a shaft 82 which is mounted for adjustment from the front of the machine as more completelyshown in application, Serial No. 83,796, to accommodate the desired pressure of the roll 73 against the die, that is for light or heavy marking.- This adjustment includes a rod or link (not shown) which extends to an adjusting knob and dial 84 at the front of the machine.

To facilitate removal or replacement of the main roll 13, the stud 18 at one .end .of the roll is made separate from the roll, fitting into a recess in the end of the roll. This stud is connected to ,a .knob or handle .85 (Fig. 5) and is normally urged by a spring 26 intoengagement with the roll 13. When it is desired to remove the roll, simply. pulling the handle 85 endwise will withdraw the stud I8, and the roll can he slipped out of the other bracket.

An ink pad or supply trough 88, arranged to furnish ink to the main ink roll 73 is pivotally mounted at 89 to the brackets M, being normally spaced slightly from the main roll 13 but movable into engagement therewith. A. leaf spring 99 secured to the movable trough or pad 88 projects into the path of the plunger [2, whereupon with each stroke of the plunger the trough will be kicked upwardly into engagement with the ink applying roll and thereby replenish the ink on the roll. I

A better application of ink to the roll, and from the roll to the die is provided if the roll is driven or rotated, and to effect this drive, there is provided a belt 9| (Fig. 2) which is secured to a pin 92 on the die carriage. The belt passes over suitable guide pulleys and idler pulleys in the machine frame, and over idler pulleys 9393 on one of the brackets 14, into engagement with a driving pulley 94 rigid with one of the studs 18 for the roll 13. As illustrated, it is on the endwise movable stud, but obviously could be located at the other end of the roll. Accordingly, as the carriage moves forwardly and backwardly, the belt 9! will be actuated, and the roll will berotated.

It is contemplated that the entire inking mechanism, due to its pivotal mounting, will be effective only on the forward or outward stroke of the die carriage, and will be controlled by a cam mechanism as fully described in application, Serial No. 83,796, such mechanism including the cam 156, hereinafterreferred to, in connection with the carriage drive mechanism.

Control linkages for the driving units The controls by means of which the driving mechanism and other operating parts of the machine are set in operation are best illustrated in Figs. 1 to 4. The crank I! for the plunger 12, carries the main fly wheel, extending for that purpose through the side of the frame In. This fly Wheel has a hub portion forming a pulley, as shown at 96 (Fig. 1), and between the hub 96 and the frame i0 is the usual clutch hub 91 (Fig. 2) carrying the 'clutch driving key 98 which is spring urged toward the hub 95, being restrained, however, by'a wedge arm Hi0, pivoted to the frame of the machine at lll'l. The hub 96 is recessed on the face opposite the clutch hub 91, and positioned in the recessed portion is a hardened pin I03. When the wedge is withdrawn by a dog arm 99 from the path of key 98, the key is projected into the recess, and will engage the hardened pin I03 and serve to drive the crank shaft for a single revolution. This structure just described is substantially the same as disclosed in the patents and applications mentioned above.

The clutch hub 91 is slightly cam shaped, being provided with a high point IN.

The single treadle I06 of the machine is connected by means of links I01 and l08 through a kick-off mechanism indicated generally at I09 to a bar Ill mounted for limited sliding movement at the top side of the frame If). The kickoff mechanism 189 and the treadle arrangement are substantially the same, as described in the patents and applications above mentioned;

The bar H0 is in turn pivotally connected to a link H I, which is pivoted to a rocker arm H2. This rocker arm controls movement of a shaft I I3 for purpose hereinafter described. Through mechanism shown in Figs. '7 to 10, which is controlled by the shaft H3, the movements of the die carriage and other operating part are controlled. The die carriage, as stated, moves from the rear of the machine to the front when the treadle ms is actuated, momentarily coming to rest while the plunger moves through its cycle toward and from the die carriage. When the carriage reaches its forward limit of travel, it trips a rocker arm 83, which through connections to the dog arm 99, withdraws the wedge I00, to permit functioning of the clutch key 98, and the shaft I1 then actuates the plunger I2. These operations take place during a single revolution of the main shaft which actuates the plunger.

Thereafter it is necessary to return the die carriage to its rear or innermost position, in order that fresh work may be placed on the work supporting plunger. To automatically effect the equivalent of a retreadling of the machine and thus return the die carriage to its original position, there is an arm H4, pivoted at H5, to the side of the frame I0. A yoke H6 also pivoted at H5 terminates in a roller H1 which rides on the clutch hub 91, and over the high point I04. The yoke H6 and arm H4 are, in effect, a single continuous lever. Movement of the yoke arm as it rides over the high point of theclutch hub cam will be transmitted to the arm H4 through a yielding connection or resilient joint comprising the fingers II8--II8 of the yoke H6, and a spring II 9 seated in a recess in the arm H4 and projecting therefrom to engage one of the fingers H8. The purpose of this resilient joint is to prevent breakage or injury to the lever H4 in the event that the clutch} 91 inadvertently fails to stop after a single revolution, it being evident that if a single rigid, connection was established between the clutch and the carriage driving mechanism, and th clutch continuedto operate, something would have to give. In the present instance, the resilient joint takes care of the situation. A lost motion connection including a spring mounted guide stud I20 serves to further support the lever H4.

The upper end of the lever H4 carries a roll I2I which rides on a cam I22, which cam serves to return the lever II 4 to its original position after it has beenactuated by the cam or high point I04. Pivoted to the-arm H4 is a link I23 connected to a rocker I24, which rocker is connected to ,a circuit maker and breaker shown in Figs. 7to 9, and hereinafter described. When the lever I I4 is actuated by the cam I04 it serves through the connections I23 and I24 to complete a circuit for the return stroke of the die carriage, and when the cam I22 returns'the lever H4 toits original position, the circuit is broken.

A= constantly rotating pulley I25 driven from the fiy wheel pulley I6, serves to rotate a shaft I26, which shaft carries an electro-magnetic clutch shown in Fig. 8. A tension spring device I21 serve to keep the bar II 0 from excessive vibration and to hold it in place against the frame I0; This spring device also serves the purpose of-supplying sufiicient friction against the'bar H0 to maintain-it in any position to which it ha been actuated. A similar spring device operating from the'side of the housing on the stud I20 performs a similar function for the arm or lever II4.- v

tating pulley I25 drives a shaft I26, the pulley itself beingdriven from the fly wheel pulley hub portion 96. The shaft I26 extends through a magnetic clutch I29, finding a bearing in a sleeve I30. The clutch I29 is similar to the clutch 3638, described in connection with the paper feed, and comprise a clutch face I3I which constantly rotates with the shaft I26. The sleeve I39 carries a second clutch face I32 which, when attracted by the magnetic coil I33, slides into engagement with the clutch facing I3I, for actuation thereby. A spring I34 operates between thrust bearings in opposition to the magnetic operations, and normally positions the sleeve I30 away from the rotating portion of the clutch when the coil I33 is not energized. A bracket I35, stationary with the frame or housing of the driving mechanism, indicated at 22, serves to support a brake surface I36. Immediately upon cessation of the magnetic clutch operation, the spring I34 comes into play and pushes the plate I32 against the brake I36, which is of the friction plate type, stopping rotation immediately.

The sleeve I30 terminates at the end opposite the plate I 32 in a pinion I 31, which obviously will be rotated, when the clutch plates I3I and I32 are in engagement, this pinion meshing with a gear I38 keyed to a shaft I39. The end of the shaft I39 serves to mount the crank arm I40 (see also Fig. 2) which is suitably connected as by a pitman to the die carriage I3. Such connections may be substantially similar to the telescoping arm arrangement shown in Serial No. 83,796. The clutch I29 will be provided with commutator rings I4II4I,' which receive current from brushes appropriately mounted in the frame 22.

When the machine is treadled the rocker H2 (see also Fig. 1) is rocked, and this rocker, being pinned to shaft I I3 oscillates said shaft. A finger I43, pinned to the shaft I I3, projects toward a circuit maker and breaker consisting of two flexible contacts I44 and I45 which are normally spaced from each other. When the finger I43 engages the contact I45, it will push it into engagement with the contact I44, as illustrated in Fig. 7, where it will be momentarily held by a cam I51, and this establishes a circuit through the clutch I29, thus actuating the shaft I39, through the gearing I 31-I38. When this occurs, the crank arm I40 will move the die carriage I3 forwardly. v At the forward limit of its travel the die carriage sets into operation the control linkages for actuating the plunger shaft I1 and the clutch hub 91 carrying the cam or high point I04, as described above.

The cam or high point I04 on the clutch hub 91, through its actuation of the arm II 4, and the mechanisms which are set into operation by movement of the arms H4 and I 24, and actuation of the magnetic clutch, then move a rocker I46, which is pinned to a shaft I41, and thereby rocks the shaft I41. Also pinned to the shaft I41 is a lever I48 having a T-shaped head I49, positioned to engage two additional circuit makers and breakers I50 and I5I causing them to operate in the manner described for the contacts I 44 and I45 of the first circuit maker and breaker.

The switch or circuit maker and breaker I50 re-establishes a circuit through the clutch I29, such circuit having been broken by separation of the contacts I 44-!45, and the clutch I29 then actuates the crank arm or lever I49 to return the die carriage to its original position. The release of the switch I 44-445 is effected by a pin plate I52 on the shaft 39, the pin plate carrying a pin I53, which pin engages a finger I54 integral with the finger I43.

The timing of the actuating mechanism for the switch II is such that the switch establishes a circuit to the bus bar mounting 59 on the return stroke only, of the die carriage, and thence through the clutch 3638 for the paper feed. The switch I5I will be broken or opened on the out-stroke of the die carriage, to insure that there will be no feed of paper until after the ornamenting operation has been completed. The shaft I38 also carries an ink roll cam I56 for depressing the ink roll mechanism on the return stroke of the die carriage, in the customary manner, fully described in the aforementioned patents and application. The pin plate I52 is cam shaped and provides a high area I51, which contacts a block I58 on the contact I45, to hold the contacts I44--I45 momentarily together after the finger I43 has receded, thus permitting the carriage I3 to complete its forward movement.

In order to provide adjustments of the circuit makers and breakers, the contacts I44-I45 as well as the contacts of the switches I50 and I5I are mounted in a fiber block I59, which block can be raised or lowered, by means of adjusting devices I60. Obviously, the vertical adjustment of the block will cause a change in timing between the block I58 and the cam I51 and this in turn affects the travel of the die carriage since the control and timing of current to the magnetic clutch I29 will be varied by this adjustment.

From the foregoing description, the operation and advantages will be readily apparent. With the die carriage in its rearmost position, inwardly of the frame II], an operator will position the work on the plunger I2, by reference to the gauges. Upon treadling the machine, the die carriage will first move to its outer or forward position, trip the control linkages for the plunger, which will rise to effect the ornamenting operation, and return to a position of rest, due to the action of the single revolution clutch 91. During this movement of the die carriage, the ink roll mechanism, through the action of the cam I56, and associated levers, will be raised to a position where the inkroll will engage the marking elements of the die, and also during the same cycle of operation of the plunger and die carriage the plunger will kick the ink supply pad 88 into engagement with the ink roll I3. to replenish ink thereon. The usual brake mechanism indicated generally at I42 will be effective to bring the parts to rest promptly upon completion of the single revolution of the shaft I'I. a

After the ornamenting operation has been completed, the die carriage, and the contact bridge 54, through its contact with the bus bar mounting 59 will set the paper feed mechanism into operation, the knife switch I5I being closed at this point in the cycle, thus presenting a fresh portion of the packing material web to the plunger I2, for the next pieceof work.

The work will be stripped from the cutters of the die in the same manner or in a similar manner to that described in Patent Reissue 20,294.

With the arrangement of controls for the die carriage and actuating mechanism as described,

it is possible to operate the plunger, the car-' it will be evident that the treadle .ment. It is further evident that the machine is designed for cutting or marking per se, or in combination.

The entire construction hereinodescribed, is intended to be fool proof, and the machine operation so simplified, safe and automatic, as to make it possible for a relatively inexperienced operator to operate the machine without difliculty and in a safe manner.

In this connection, it may be found desirable to lock the machine against the possibilityof treadling, in order to make various adjustments. Accordingly, a pivoted latch IBI is mounted on the side of the frame, which latch comprises a pivoted plate having a pin I62 which may be swung into the path of a rocker arm forming part of the connections to the bar I It, as shown in Fig. 1. With the latch in the position shown,

I66 is ineffective.

Among the advantages are the need for gauging the work but once for both cutting out and marking operations, the saving in ink required, by light but legible marking, the fact that the present device may be successfully used for marking on all thicknesses and characters of work with the proper degree of pressure for printing, the attainment of uniform marking of various thicknesses and characters of material, in a uniform manner, the extremely accurate control and regulation of the several mechanisms, etc.

Furthermore, all of the advantages of ink marking over straight indentation or impression marking, or other types of marking, as fully set out in the patents upon which this case represents improvements, are attained, these advantages being well recognized at the present time.

It will be understood that this description is intended as illustrative and that the invention is not to be limited thereby, other than as defined in the appended claims. By way of example, the die may be arranged to out upwardly instead of downwardly, the pressures might be applied from above instead of below the work, the paper feed might be driven from an entirely separate motor or other source of power than the motor I8; the machine might be operated from a different source than the motor I8, which could be used solely for the paper feed, in fact many modifications may occur to those skilled in the art.
